Not very scientific, Bill. Richard is objective and clear. You got upset. shame…
Bill is right about the changing of the salinity affecting air-water heat exchange, what he should have made clear is that this heat exchange is a major contributor to the winds that drive the Gulf Stream. I think the other guy was confusing the Gulfstream with the jetstream, ironically heat exchange has a lot to do with both. The point that I think that both of them missed, is that we have geological records of changing salinity in the oceans over time during the existence of modern life. Ocean salinity is directly tied to algae production which is directly tied to the amount of oxygen versus other greenhouse gasses in our atmosphere, which is directly tied to global climate change. The warmer the planet gets, the higher the atmospheric water content (which makes it even warmer still), the larger the storms, it’s a huge giant, vicious cycle. The problem is we call it global warming when really it should just be called global climate change, because the average temperature of the Earth really has not gone up in the past 10 years yet we’re seeing devastating effects of global climate change on a much more frequent basis. Larger, more intense tornado seasons with tornadoes that have mile wide paths of destruction, 600 miles long, hurricanes have always traveled north, yet they’re traveling farther and farther north with much greater intensity, more frequently. I am 27 years old, in my lifetime I have seen drastic climate change, no person, scientist or otherwise, can argue with the fact that in my home state of Pennsylvania transitional seasons like spring and fall are growing shorter and shorter while winter and summer are growing longer and longer and much more harsh. I grew up with summer temperatures that rarely cracked 100, now I rarely see summer days that peak below 100. In the first 20 years of my life, I saw massive snowstorms that fell into a predictable pattern. You could set your watch by the Farmer’s Almanac, yet just this year I saw snowfall in April. In the first 20 years of my life, I can only remember this happening one time, yet in the last several years it’s happened multiple times. Powdery fluffy snow has given way to ice storms, just as Spring showers have given way to torrential downpours that cause regular flooding, tremendous crop damage and do almost nothing to help our groundwater. Global climate change has been waging war on Pennsylvania’s historically predictable weather. In the past few years we have seen more record highs and lows then have been recorded since the beginning of weather recording. We Pennsylvanians along with our New York, New Jersey, Delaware, Maryland, Virginia and Ohio neighbors are on the front lines of global climate change. We must do whatever we can to stabilize our global climate, before we’re unable to.
